Abstract: In vitro studies using cells transfected with acid-sensing ion channel 3 (ASIC3) or acid-sensing ion channel 1 (ASIC1) cDNA, demonstrated that the miRNAs against mouse ASIC3 (miR844 and miR847) selectively inhibit mouse ASIC3, but not ASIC1 as detected by protein expression and responses to pH. When the RNAi agents, miR844 or miR847, were used in vivo, delivered into the muscle of mice using a replication-defective herpes simplex viral (HSV-1) vector, primary and secondary hyperalgesia were reduced after carrageenan-induced muscle inflammation. Accordingly, the present invention provides RNAi agents that target ASIC3, methods of preparing such RNAi agents, and methods of using them to modulate in a cell the level of ASIC3 or activity of an ASIC including at least one ASIC3. Modulation of ASIC3 activity or levels can be used for different purposes such as treating pain associated with the expression of ASIC3 and the like.
Abstract: In one aspect, the invention relates methods for inhibiting or preventing muscle atrophy or increasing muscle mass by providing to a subject in need thereof an effective amount of ursolic acid, a derivative thereof, or an analog of the ursane scaffold.

Abstract: Biodegradable polymeric microparticle compositions containing one or more active agents, especially those useful for treating or preventing one or more diseases or disorders of the eye, and methods of making and using thereof, are described. In a preferred embodiment, the microparticle compositions contain one or more active agents useful for managing elevated intraocular pressure (IOP) in the eye. Relatively hydrophilic, and preferably carboxylated, polymeric materials such as PLGA are used for a drug such as timolol maleate, which is relatively water soluble, to increase drug loading. Higher molecular weight polymers, as well as the ratio of LA (which has a longer degradation time, up to one to two years) to GA (which has a short degradation time, as short as a few days to a week), are used to provide release over a longer period of time.

Abstract: The distributive elastic properties in nonlinear structures is characterized using an inverse elastostatic approach of stress analysis using assumed elastic models without knowing the realistic material parameters. Stress distributions are computed independently of strain measurements. A database of pointwise stress and strain data in regions of the nonlinear structure permits the elastic properties of the structure to be characterized point-by-point to provide the property distribution.

Abstract: Provided are methods for determining optimal features for classifying patterns or objects. Also provided are methods for image analysis. Further provided are methods for image searching.
Abstract: An image of an object is synergistically reconstructed using two or multiple imaging modalities. A first reconstructed image, showing structural information of the object is produced using a first imaging modality. The first reconstructed image is segmented, and known optical properties of the object are then mapped to the first reconstructed image. Optical signal emissions from the object are detected and registered with the first reconstructed image. A second reconstructed image volume is then produced using a second imaging modality, based on the mapped optical properties after registration between the first image and the data from the second modality. The second reconstructed image depicts some optical property, such as a bioluminescent source distribution, or optical properties, such as, attenuation and scattering properties, of the object.

Abstract: A system and methods for the efficient segmentation of globally optimal surfaces representing object boundaries in volumetric datasets is provided. An optical surface detection system and methods are provided that are capable of simultaneously detecting multiple interacting surfaces in which the optimality is controlled by the cost functions designed for individual surfaces and by several geometric constraints defining the surface smoothness and interrelations. The graph search applications use objective functions that incorporate non-uniform cost terms such as “on-surface” costs as well as “in-region” costs.
